A button assembly for an electronic device includes a housing and a button. The housing defines an opening having two latching blocks. The button is received in the opening. The button includes a button body, two opposite engaging blocks, and two arcuate arms. The engaging blocks are formed on opposite sides of one end of the button body, the arcuate arms are formed on opposite sides of another end of the button body. Each arcuate arm forms an archimedean spiral.
